Efficient Identity-Based Outsider Anonymous Public-Key Trace and Revoke with Constant Ciphertext-Size and Fast Decryption

It is an important challenge to find out suitable cryptography for WSN due to limitations of energy, computation capability and storage resources. Considering this sensor feature on limitations of resources, a security architecture based-on public key cryptography is proposed. The security architecture is based on identity based cryptosystem, but not requires key handshaking. The analysis shows that the security architecture ensures a good level of security and is very much suitable for the resources constrained trend of wireless sensor network.

Identity Based

"Due to the lack of a centralized server in “Peer-to-Peer” (P2P) networks, users are responsible for the security of these networks. One of the security issues in P2P networks is the security of the message routing. Messages could be altered or modified by attackers while being routed. The conventional security method to avoid this has been “Public Key Cryptography” (PKC). To avoid the certificate management issue in PKC, “Identity-based Encryption” (IBE) has been suggested in which any arbitrary string could be used as a public key. Since IBE is a computationally expensive method, current proposed IBE-based methods are not effective in the message routing phase in P2P networks and highly affect the performance of message delivery time in these networks. This thesis proposes two IBE-based protocols that can be applied effectively to the message routing phase of structured P2P networks, yet provide a satisfactory message delivery time performance. Both protocols benefit from Identity-based key exchange scheme and, therefore, none of them impose any extra communication on the network to secure message routing. Protocol 1 significantly improves the performance of message delivery time compared to the current IBE-based proposed methods. Protocol 2, which requires nodes to store data, has a performance similar to the situations in which no security measures are applied for message routing."

Identity Based

Wireless sensor networks (WSN) have problems such as limited power, weak computing power, poor communication ability, and vulnerability to attack. However, the existing encryption methods cannot effectively solve the above problems when applied to WSN. To this end, according to WSN’s characteristics and based on the identity-based encryption idea, an improved identity-based encryption algorithm (IIBE) is proposed, which can effectively simplify the key generation process, reduce the network traffic, and improve the network security. The design idea of this algorithm lies between the traditional public key encryption and identity-based public tweezers’ encryption. Compared with the traditional public key encryption, the algorithm does not need a public key certificate and avoids the management of the certificate. Compared with identity-based public key encryption, the algorithm addresses the key escrow and key revocation problems. The results of the actual network distribution experiments demonstrate that IIBE has low energy consumption and high security, which are suitable for application in WSN with high requirements on security.
